-0.12-0.20

Question 2

Normal QRS length

Answer 2

2-3 small squares

Question 3

5 step EKG interpretation

Answer 3

Rhythm
Heart Rate
P waves
PR Interval
QRS Complex

Question 4

rhythm

Answer 4

Examine R-R intervals (top to top)

Question 5

Heart Rate

Answer 5

fast or slow?
- number of QRS complexes between two black tick marks

Question 6

p waves

Answer 6

1. Are P waves present?
2. Is there 1 P Wave for every 1 QRS?
3. Are P Waves smooth, rounded, and upright or inverted?

Question 7

PR interval

Answer 7

PR intervals >0.20 sec?
Are PR Intervals constant across EKG strip?

Question 8

QRS complex

Answer 8

Is the QRS Complex < 0.12 sec?
Is the QRS Complex > or = 0.12 sec?
Are the QRS Complex similar across the strip?

Question 9

a flutter

Answer 9

• regular rhythm
• p wave is sawed toothed
• PRI: none

Question 10

a fib

Answer 10

• rhythm is irregular
  -rate varies
• no P wave
• no PRI

Question 11

First degree AV heart block

Answer 11

• PRI > 0.20 (fast)

Question 12

Second Degree AV Heart Block: Mobitz Type I (Wenckebach)

Answer 12

• PRI Progressive longer then drops a QRS

Question 13

Third Degree (Complete) Heart Block –3o AV block

Answer 13

• PR intervals have no relation to QRS
• regular rhythm
• wide or normal QRS

Question 14

Idioventricular Rhythm

Answer 14

• no PR interval
• no p wave
• rate 20-40
• wide QRS

Question 15

V Tach

Answer 15

• no p wave
• no PR interval
• HR greater than 150
• wide QRS

Question 16

v fib

Answer 16

• No normal EKG waves are present. No heart rate can be observed
• irregular rhythm
• unkown rate
• no P wave, no PR interval. no QRS complex

Question 17

PVC

Answer 17

• Look for a wide QRS complex, equal or greater than 0.12 sec. The QRS complex shape can be bizarre. The P wave will be absent
• rhythym: early beat
• WNL P wave
• WNL PR interval
